ORDER ESTABLISHING SPECIAL
CONTEMPORARY RESOURCE PLANNING ISSUES

Issue Date:October 31, 2012 Effective Date:November 1, 2012

A
provision in the Missouri Public Services Commission’s revised electric utility
resource planning rule, 4 CSR 240-22.080(4), requires Missouri’s electric
utilities to consider and analyze special contemporary issues in their triennial
compliance filings and in their annual update reports. The regulation provides that by September 15
of each year, Staff, Public Counsel, and other interested parties may file
suggested issues for consideration.The
regulation allows the utilities and other parties until October 1 to file
comments regarding the suggested issues. The regulation requires the Commission
to issue an order by November 1 of each year specifying the list of special
contemporary issues that each electric utility must address.

The
Commission’s Staff, the Missouri Department of Natural Resources (MDNR), and
the Sierra Club filed suggested special contemporary issues for Union Electric
Company d/b/a Ameren Missouri to analyze and respond to in its next integrated
resource plan (IRP) filing.Ameren
Missouri filed responses to those suggestions.The Commission must now determine what special contemporary issues Ameren
Missouri should address.

This
is not a contested case.The Commission
does not need to hear evidence before reaching a decision and does not need to
make findings of fact and conclusions of law in announcing that decision.[1]The Commission’s rule gives the Commission
broad discretion in determining what issues a utility should be required to
address, indicating:

[t]he purpose of the
contemporary issues lists is to ensure that evolving regulatory, economic,
financial, environmental, energy, technical, or customer issues are adequately
addressed by each utility in its electric resource planning.Each special contemporary issues list will
identify new and evolving issues but may also include other issues such as
unresolved deficiencies or concerns from the preceding triennial compliance
filing.[2]

It
is also important to note that the Commission’s IRP rules require Ameren
Missouri to file a full IRP study once every three years.Ameren Missouri does not need to file its
next full IRP study until April 1, 2014.[3]That means Ameren Missouri would need to
address the special contemporary issues identified in this order in its 2013
annual update report, not in a full IRP study.This distinction is important because in its annual update report, the
electric utility is only expected to address “changing conditions since the
last filed triennial compliance filing or annual update filing.”[4]For that reason, the requirement to examine
special contemporary issues should not expand the limited annual update report
into something more closely resembling a triennial compliance report.

After
considering these factors, the Commission will adopt the list of special
contemporary issues set forth in this order.

THE
COMMISSION ORDERS THAT:

1.Union Electric Company d/b/a Ameren Missouri
shall analyze and document the following special contemporary issues in its 2013
annual update report:

a.Investigate
and document the impacts on the Company’s preferred resource plan and
contingency plans of aggressive regulations by the FERC, regional transmission
organizations (“RTOs”) or Missouri statutes or regulations to allow aggregators
of retail customers (“ARCs”) to operate and market demand response services in
Missouri; and

b.Analyze
and document the impacts of opportunities to implement distributed generation,
DSM programs and combined heat and power (CHP) projects in collaboration with
municipal water treatment plants and other local waste or
agricultural/industrial processes with on-site electrical and thermal load
requirements, especially in targeted areas where there may be transmission or
distribution line constraints.
